Design Of Intelligent Home Control System Based On Raspberry Pie

With the development of communication technology and the Internet of things,smart home has been developing rapidly,and has gradually penetrated into the lives of ordinary people.Because of the high pursuit of people's quality of life,the research of smart home has become a hot topic.Since the first intelligent summer designed by the United States,smart home has attracted people's attention.The arrogant design cost of smart homes has greatly constrained the development,but with the development of communication technology and the popularity of mobile smart phone,it has brought great vitality to the smart home.Smart home has broad application prospects.Therefore,research and development of smart home is in line with the needs of contemporary social development.Based on the WIFI technology and the Raspberry Pi platform,this paper designs the smart control of the light and curtain motor for the mobile terminal and the computer terminal,respectively.The main work includes the following:First of all,wireless communication technology is more cost-effective and convenient than wired communication technology.The system is based on the Raspberry Pi 3B.It uses the Raspberry Pi on-board wireless network interface module to connect with the laboratory's WIFI network,plus the corresponding peripheral circuits to control the full-color LED.A mobile phone mobile app is designed to intelligently control the brightness and color changes of the LED.Then,the computer interface is designed,and the function interface of the control motor is programmed.The computer interface is installed safely,ensuring the security of the system application.The motor control uses wiring PI to drive the GPIO pins,occupying 6 pins in total,2 for outputting the PWM signal,and 4 for outputting the control signal.The LM293 motor control board is used to drive the motor.Two A58SW31 worm gear motors are used.The PWM sets the speed adjustment of the 10 speed motor and the forward and reverse direction drive functions.Finally,the function test and performance test of the system are carried out.The test results show that the system is stable and reliable,and the whole system meets the requirements of the initial design,which proves that the system has great application value.
